8216137: assert(Compile::current()->live_nodes() < Compile::current()->max_node_limit()) failed: Live Node limit exceeded limit

Adding simplistic node budget support for loop-transformations. This /should/attempts to/ resolve most cases of: "assert(Compile::current()->live_nodes() < Compile::current()->max_node_limit()) failed: Live Node limit exceeded limit".
